Abstract
This research paper aims to explore the current information available on prevention of cancer and organise the same into a systematic review paper, for the second task of the Research Contest at Dreamers' Creations.
The resources used for this paper are all sourced from Youtube, as per the rules defined for this task of the contest.
There is no doubt that Cancer prevention is a critical aspect of public health, and spreading awareness of prevention strategies is the need of the hour, especially as Cancer is still largely incurable. Therefore, this paper attempts to provide a unique perspective on cancer prevention, highlighting the importance of accessible and engaging multimedia content in promoting healthy behaviors and reducing cancer risk.
Introduction
Cancer is a complex and diverse group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. It can affect any part of the body and has the potential to invade nearby tissues and organs, as well as spread to distant sites through the bloodstream or lymphatic system. According to the World Health Organization (WHO), this disease is the second leading cause of death worldwide, responsible for an estimated 9.6 million deaths in 2018. However, it must be noted that Cancer incidence and mortality rates vary across different regions of the world, and low- and middle-income countries bear a disproportionate burden, accounting for approximately 70% of global cancer deaths.
The statistics make it clear why Cancer prevention is a crucial aspect of public health. We, as a global society, must aim to spread awareness of the preventive measures against Cancer, because by increasing knowledge and understanding, we can collectively work towards reducing the burden of cancer and improving outcomes for individuals and communities affected by this disease. This research paper is one attempt to do the same.
Cancer Prevention Strategies
Healthy Lifestyle Choices
Certain lifestyle choices have been strongly linked to an increased risk of developing cancer. Many risk factors, however, are modifiable, meaning they can be changed or controlled. This is achieved by making healthy choices. Individuals can take control of several risk factors and significantly reduce their susceptibility to cancer, by implementing a healthy lifestyle.
In this subsection, we will explore various ways to lead a healthy life and their importance for Cancer prevention.
Tobacco Control and Smoking Cessation
Tobacco use is the single largest preventable cause of cancer worldwide, accounting for approximately 22% of cancer-related deaths. It is thus, no surprise that effective tobacco control measures and smoking cessation, can greatly reduce the incidence of Cancer.
Some of these control measures may include increasing tobacco taxes, implementing smoke-free laws in public places, banning tobacco advertising and promotion, requiring graphic warning labels on on cigarette packages, and providing access to smoking cessation services.
Preventing tobacco use among youth is vital in reducing future cancer rates. Implementing strict regulations on tobacco sales to minors, conducting educational campaigns in schools, and countering tobacco industry marketing tactics can help discourage young people from starting smoking.
Furthermore, providing support and resources for smokers who want to quit is essential. This can include access to counseling services, nicotine replacement therapies (such as patches, gum, or inhalers), prescription medications, and behavioral
interventions. Supportive environments and encouragement from healthcare professionals, family, and friends can greatly increase the chances of successful smoking cessation.
Since tobacco and smoking are important issues that have significant global impacts, we need collaborative efforts between countries, international organizations, and public health agencies that can help share best practices, strengthen policies, and support each other in reducing tobacco use and its associated health risks.
Diet And Nutrition
Statistics reveal that an improper diet and poor nutrition are significant risk factors for developing cancer. In fact, it is estimated that around 30-35% of cancer cases are directly linked to dietary factors. This highlights the importance of adopting a healthy diet to reduce the risk of cancer.
A healthy diet is a powerful tool for cancer prevention due to several reasons. Firstly, it helps in maintaining a healthy weight. Obesity is a known risk factor for various types of cancer, including breast, colorectal, and pancreatic cancer. By consuming a balanced diet that is low in processed foods, added sugars, and unhealthy fats, individuals can manage their weight effectively and reduce their risk of developing cancer.
Secondly, a healthy diet provides essential nutrients and antioxidants that support the body's natural defense mechanisms against cancer. Fruits, vegetables, whole grains, and lean proteins are rich in vitamins, minerals, and phytochemicals that have been shown to have anti-cancer properties. These nutrients help to strengthen the immune system, repair damaged DNA, and reduce inflammation, all of which contribute to cancer prevention.
When it comes to specific dietary choices for cancer prevention, there are several options to consider. One such choice is consuming a plant-based diet. Studies have consistently shown that individuals who follow a predominantly plant-based diet have a lower risk of developing cancer. Plant-based diets are typically high in fiber, antioxidants, and phytochemicals, which have been associated with a reduced risk of various cancers, including colorectal, breast, and prostate cancer.
One of the most important initiatives to take, if you want to prevent cancer is cutting down on processed foods, especially processed meat.
High consumption of red and processed meats has been linked to an increased risk of colorectal cancer. The International Agency for Research on Cancer (IARC) has classified processed meats as Group 1 carcinogens, meaning they are known to cause cancer. It is advisable to limit the intake of these meats and opt for lean protein sources like poultry, fish, and legumes.
Furthermore, alcohol consumption is another known risk factor for several types of cancer, including breast, liver, colorectal, and esophageal cancer. So, a healthy diet is best devoid of alcohol, however, for those struggling to forgo alcohol consumption, The American Cancer Society recommends limiting alcohol intake to one drink per day for women and two drinks per day for men.
Physical Activity and Exercise
A sedentary lifestyle, characterized by prolonged periods of sitting or physical inactivity, has been linked to numerous health risks, including an increased risk of cancer. Research has shown that engaging in regular physical activity can significantly reduce the risk of developing certain types of cancer. In this subsection, we will explore the strategies related to physical activities that can help mitigate this risk.
According to the American Cancer Society, an estimated 18% of all cancer cases in the United States are associated with a sedentary lifestyle. Physical inactivity has been specifically linked to an increased risk of developing colorectal, breast, and endometrial cancers. In fact, studies have shown that individuals who engage in regular physical activity have a 20-30% lower risk of colon cancer compared to those who are inactive.
Regular physical activity can also help reduce the risk of breast cancer. A study published in the Journal of the National Cancer Institute found that women who engaged in moderate to vigorous physical activity for at least 150 minutes per week had a 20% lower risk of developing breast cancer compared to those who were inactive.
To reduce the risk of cancer associated with a sedentary lifestyle, it is recommended to incorporate regular physical activity into daily routines. The American Cancer Society suggests aiming for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities at least two days a week.
Engaging in physical activities such as brisk walking, jogging, cycling, swimming, or participating in sports can help individuals meet these recommendations. Additionally, incorporating activities that promote flexibility and balance, such as yoga or tai chi, can further enhance overall well-being.
It is important to note that even small increases in physical activity can have significant health benefits. For example, a study published in the British Journal of Cancer found that individuals who increased their physical activity levels by just 30 minutes per day had a 14% lower risk of developing colon cancer compared to those who remained inactive.
Early Detection and Screening
When cancer is detected at an early stage, treatment is often more effective and survival rates are higher. However, when diagnosis is delayed, the cancer has more time to grow and spread. This can make treatment more difficult and reduce the effectiveness of therapies.
For example, the 5-year survival rate for breast cancer detected at stage 1 is 99%. However, for stage 4 breast cancer, the 5-year survival rate drops to 22%. Similarly, the 5-year survival rate for colorectal cancer detected at an early stage is 90% but falls to 11% for late-stage diagnosis.
Delayed diagnosis is often due to a lack of awareness of symptoms, failure to act on concerning symptoms, or difficulties accessing health care. Some key statistics:
• Over 50% of cancers are diagnosed at a late stage, when survival rates are significantly lower.
• Late-stage diagnosis accounts for up to 75% of cancer deaths. With earlier detection, many of these deaths could potentially be avoided.
• If all women got regular mammograms, up to 30% of breast cancer deaths could be prevented.
In summary, late diagnosis of cancer greatly reduces a patient's chance of survival and accounts for the majority of cancer deaths. Earlier detection through awareness of symptoms, screening tests, and access to health care could significantly reduce cancer mortality rates.
Conclusion
Cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells. It is a leading cause of death worldwide, accounting for nearly 10 million deaths in 2020.
Some key statistics discussed in this paper:
• Cancer is the second leading cause of death globally, accounting for nearly 1 in 6 deaths.
• Lung, prostate, colorectal, and breast cancers are the most common types of cancer and cause the majority of cancer deaths.
• Around 70% of cancer deaths occur in low- and middle income countries.
• Cancer rates are projected to continue rising as populations grow and age.
Fortunately, there a number of strategies that can help prevent cancer or detect it at an early stage. One of the most important strategies is quitting tobacco use and smoking, for those that have fallen prey to these substances.
For non-smokers, avoiding secondhand smoke are key to reducing the risk of many cancers, especially lung cancer. Tobacco smoking causes over 22% of cancer deaths worldwide.
